To aZZ whom it may concern:

Be it known that I, WILLIAM E. MOOREt;

a Chicago, in'the county of Cook and tate of Illinois, have inventedcertain new and useful Improvements in Earth-BoringMachines, of whichthe following is a specification.

This invention relates to earth boring machines.

It is particularly applicable to earth boring machines of the mobiletype. p The earth boring machine in hich' the invention has beenembodied com. rises, in general, a vehicle upon which a turntable ismounted. A tiltable augerftower is mounted on ,one side of theturntable. and adjacent the tower is a power driven rotatable andlongitudinally movable auger shaft for carrying and operating the boringauger.

An earth boring machine of this general type is set forth. in my'copending. application Serial No. 252,994, filed September7, 1918; a I3 drive which may raise or lower the auger at any angle of inclinationof the auger shaft. Other objects and advantages will appear from thespecification and ola1ms..

An embodiment of the invention'is illustratedin the accompanyingdrawings.

In the drawings body my invention.

F'g. 2 is a top plan view of the parts shown in Fig. 1.

Fig. 3 is a longitudinal section taken sub stantlally on line 3+3 3 ofFig. 2.

Fi 4 is a horizontal sec'tion'taken substantially on line 44 of Fig; 1,the parts being shown on a slightly enlarged scale.

of Fig.4 and line Flg. 5 is a section taken on line .5-5 of Serial No.252,994. This machine includes ing sh'a t 18. Intermeshin An object ofthis invention is to provide-- the main frame. 10 supported for thepur-.

wheels 11. The supin my said prior application.

1 Driving belt 16 transmits power from the motor to a driving pulley 17on a driving shaft 18 which extends transversely across an intermediatepart of the support- 'ing frame 12. A counter or driven shaft 19- isarran ed in parallel relation to the drivgears 20 and 21 are looselymounted 011 s afts 18 and 19 on one side of the frame and are adapted tobe connected'to their respective shafts by means of clutches 22 and 23,respectively. The clutches'are so arranged that when one the same asshown and described through suitable of the gears is clutched to itsshaft the other gear will be loose on its shaft. clutches are operatedby by link 25 to operator is pivotally mounted wlth reference to theframe on a. pivot 27. These shafts 18 and 19 are alsooperativelygconnected by means of a chain'28 engaging a sprocket 29 onshaft a lever24 connected 18 and a lar er sprocket 30 onshaft 19. OnFig. 1 represents a side elevation of thev rear part of a machineconstructed to em-.

one end' of t e shaft 18 'I rovide a sprocket 31 having a chain 32 fordriving a sprocket 33 on. a shaft 34 to be presentlyv described. Aclutch 35 is actuated by an 'operators lever These slever 26. \Le'ver 24i 36 so as to operatively connect sprocket 31 with shaft 18 for theshaft,34.i I v A sprocket 37 is mounted to rotate-with purpose ofdriving gear wheel 21 and drive a chain 38 to drive a sprocket, 39 on ashaft 40 A bevef gear 41 is secured near the other end of this shaft anda sleeve 42 is 'loose on said shaft. Ex-

tending laterally from sleeve 42-is a boss 43-which forms a bearing forthe end of an inclined shaft 44, which has onits lower end, a bevel ear45 which meshes with bevel gear 41 on s aft 40. Bevel gear 45 is held inplace by means of spring clips 46, the ends of which engage in a grooveformed in the hub of bevel gear 45, see the dotted line disclosure inFig. 3 of the drawing This inclined shaft 44 is provided with alongitudinally extending spline or key-way 47 to receive a key orfeather 48,-connecting a bevel gear 49in slidablev relation- 'thereto.This bevel gear 49 is rotatably connected to a box 50 by means of springclips 51 engag-w ing in a groove 52 formed in the hub of gear wheel 49.Thus box is likewise slidable relative to shaft 44. This box 50 formsthe journal or hearing for a short transverse shaft 53. To shaft 53 iskeyed a bevel gear 54 meshing with bevel gear 49. Shaft 53 is j ournaled1n the bracket members 55depending from auger supporting frame or tower.Between these bracket members 55 I secure to the shaft 53 asprocket "56which is operatively connected by means of a chain 57 with a sprocket 58at the top of the auger thereof. This auger shaft 62 is rotated to drivethe auger 63 by means of a bevel gear train 64 enclosed in a gear box 66and driven by shaft 34. The sliding head 61 is sultably connected to the"sprocket chain .57 whereby movement of the sprocket will cause u the.auger tobe raised and lowered, as is well understood. v

Auger tower 59 is pivotally mounted with reference to the supportingframe 12. It is supported on one side-by means of shaft 34 and on theother side by means of a trunnion 65 which is journaled in a bearing onthe elongated side frame member 14 of frame 12. Any suitable means maybe utilized for moving the auger tower 59 on its I pivot so as to borethe hole at variousangles relative to the main frame, one form of suchmeans being illustrated in my said prior ap plication. J

swaying movement by means of brace members 67 which are connected nearthe top thereof and extend outwardly to the outer side frame members '14of frame 12, having a pivotal connection or hearing therewith, as shownat 68, Figs. 1 and 2. The auger tower is also provided with bracing andholding members extending longitudinally of the" frame, these memberscomprising rods 69 pivotally mounted, as at 70, to the inter mediatelongitudinal members 14 of the frame 12 and slidably passing throughsleeves 71 provided on brackets 72 which are shaft drive for raising andlowering the auger-to and fromoperative position and feeding the same,which may be'operated regardless of the inclination; of the auger tower59, it being seen that gear 48 and box 50 are slidable along-shaft'44and thatthe 5 same has a, pivotal bearing in the; boss'43 on the sleeve42, which may turn on shaft 40.

In connection with this mechanism I also provide a derrick or frameconstruction which includes a hollow post or pipe ,74

through which passes an anchor rod 75, this rod also passing through themain frame 10 and formingthe pivot or center on .Which theframe 12 turnsrelative to the main frame 10. This pipe 74 passes through a station-" 5ary socket or supporting member 76 and may turn therein.

which are provided with turn buckles 78 whereby they may be adjusted asvdesired.

The outer ends of members 77 are secured to the outside longitudinalmembers 14 of the frame 12. The top end of hollow post 74 is braced-by astrut or support 79. To this post 74 is pivotally connected a crane orderrick arm 80, the outer end of yvhich is .connected to the upper endof post 74 by means of a bracing link 81. This crane or derrick has theusual pulley 82through which passes a cable 83 which is wound upon adrum or 100.

Windlass 84 which may be driven in any desired manner. I
